Type: Agouti paca ( = Mus paca Linneeus), from South America. 
Agouti: The native name, probably the same as acuti, attentive, vigilant—in ref- 
erence to the habits of the animals. (See explanation under Cutia.) 
Agricola (subgenus of Arvicola) Buastus, 1857. Glires, Muridze, Microtinze.

Type: Mus agrestis Linnzeus, from Europe. 
Agricola: Lat. ager, field; colo, to till, to cultivate—‘ field mouse,’ from its oecur- 
rence in fields, etc. 
Agrichegus Gore, 1874. Ungulata, Artiodactyla ? 
Glossary Fossil Mamm., 5, 1874. 
* A genus of Ruminant, having some affinities with Merycopotamus; found in 
Miocene deposits in North America.’’—Gorr. This name has not been found 
except in this place. It is evidently not a misprint for Agriocherus, as the 
latter name follows it in the Glossary and is defined as ‘‘a genus of Mammals 
. allied to the Oreodon.’’ 
Extinct. 
Agriocherus Lreipy, 1850-51. Ungulata, Artiodactyla, Agriochceride. 
Proc. Acad. Nat. Sci. Phila., 121-122, 1850-1851; Corr, Proc. Am. Philos. Soc., 
XXI, 559-570, 1884. 
Type: Agriocherus antiquus Leidy, from the Oligocene of South Dakota. 
Extinct. Based on ‘‘a great portion of the face and inferior maxilla, contain- 
ing six molar teeth on each side, and the posterior two molars of both sides 
superiorly of another individual." 
Agriocherus: &yptos, wild; xo 1pos, hog. 
Agriodus (subgenus of Canis), H. Smiru, 1840. Fere, Canidze.

152, 1858; V, 258-261, 298, pl. 23*, 2 figs. in text, 1865. 
Type: Agriodus auritus H. Smith (=Canis megalotis Desmarest), from the Cape 
of Good Hope. 
““The anomalous character of the teeth indicates the food of the Agriodus to differ 
considerably from that of other Canidx, and no doubt the manners of the species 
are equally influenced by this conformation. These considerations induced us 
to prefer the name here assigned to the subgenus to that of Megalotis, which 
Iliger originally bestowed upon the Fennecs." Antedated by Otocyon Mül- 
ler, 1836. 
Agriodus: &y pios, wild (possibly in the sense of aberrant); 660s, tooth. This 
genus has 46 or 48 teeth, including a greater number of molars than is pos- 
sessed by any other heterodont mammal,
